rGa6b19979bf13: tzcode: Fix TZ for non-setugid programs

Summary

The previous commit had the desired effect for setugid programs, but
broke TZ for everyone else. I didn't notice because my test cases
swap out /etc/localtime instead of setting TZ, so add a test case
that sets TZ.

Fixes: b6ea2513f776 ("tzcode: Limit TZ for setugid programs")
